A long time ago, there were no umbrellas. But Lu Ban thought, what should we do if it keeps raining? One cannot stay in the pavilion without leaving. It would be great if we could make the pavilion very small and let everyone carry it with them! How can we make the pavilion light and delicate? ?One day, the weather was extremely hot. Lu Ban saw many children playing by the lotus pond, and each child had a lotus leaf on his head.

Lu Ban’s heart suddenly brightened. He hurried home, found a piece of bamboo, split it into many thin strips, and made a frame like a lotus leaf. He also found a piece of sheepskin, cut it into a round shape, and put it on the bamboo frame. He shouted happily that this thing could not only block the rain and the sun, but also be very light. Later, he changed it into a movable one: when in use, he opened it; when not in use, he closed it . This is the earliest umbrella.
